Device for adjusting perpendicularity of actuation rod of portable micrometer press-in instrument

Abstract

The invention discloses a device for adjusting the perpendicularity of an actuation rod of a portable micrometer press-in instrument. The device comprises a bottom plate, a driving mechanism, a centeradjusting table and a lifting mechanism which surrounds the bottom plate, wherein the driving mechanism comprises a stepping motor, a motor support, a driving bevel gear and a driven bevel gear; thedriven bevel gear is connected with a ball screw; the driving bevel gear is connected with the output end of the motor; the motor is connected with the motor support; the motor support is fixed on theupper end surface of a base of the lifting mechanism; the lifting mechanism is fixed to the bottom plate; the center adjusting table is connected with a moving platform in the lifting mechanism and comprises an adjusting platform, locking bolts, an optical axis and a gyroscope; a through hole is formed in the center of the adjusting platform and used for placing the actuation rod; the locking bolts are uniformly distributed around the through hole; the actuation rod is clamped through thread self-locking; and the gyroscope is fixed on the adjusting platform through a stud and is used for detecting an inclination angle between the actuation rod and the horizontal plane. The device realizes the high-precision adjustment of the perpendicularity between the actuation rod and the horizontal reference plane.

Description

technical field [0001] The invention relates to the technical field of verticality adjustment, in particular to a device for adjusting the verticality of an actuating rod of a portable micro-indenter. Background technique [0002] Due to the errors in the processing or assembly process of the current portable micron indentation instrument, when the indentation test is performed on the actuating rod, the actuating rod of the indenter is often not perpendicular to the surface of the tested sample. In this case It will cause the measured load-depth curve to deviate from the real curve, so that the correct mechanical performance evaluation of the tested actuator cannot be performed. Therefore, it is necessary to design a device that can adjust the perpendicularity between the actuating rod and the reference plane. Contents of the invention [0003] The invention provides a device for adjusting the verticality of an actuating rod of a portable micro-intrusion instrument, which...
